Not direct evidence, but presumably a direct quote in an
article at the-race.com,
Oscillations were visible on both drivers’ onboard cameras during FP1, which suggested the return of the Honda engine-related vibrations that the team struggled with at the start of the year.
When The Race put that to him, Newey said: “The oscillations, yes, that's really a question for Honda. They can see it on the data and they are working on the solution.”
Sounds a bit odd, they had vibrations at the start of the year, fixed them, and they've come back with the new car but old engine, but Honda can do something to fix or improve them?
I was going to say it's also a bit curt to bat it Honda's way, given the past history, rather than say "we're working on it and think we can dial it out" or something to that effect, but maybe I'm over analysing the words.
Somewhere or other I also saw a supposed quote from Alonso that things were improved in FP2. Puzzling / intriguing if true.
Edit:
over at autosport,
"Yeah, today we had some vibrations on the main straight, especially in FP1," he said. "I think the guys fixed it more or less for FP2, so yeah, there are no concerns for tomorrow."
